Please Ignore Marty.
No offense, but there's no way you hit him on accident. I don't buy that for a second. You're allowed to fight over resources, but a warning must be given before attacking. Anyways, considering your story is true, your ban wasn't permanent, just keep in mind that we take combat logging very seriously. I'll check your ban time when I get home and talk to the staff member who banned you and I'll see if they can shed some light on the situation.
